Hi all,

Iam focusing on the autoclave process for composite part manufacturing. In aircraft industry this process needs inert gases which can be either nitrogen or carbon dioxide, hpwever, nitrogen is used in most cases.

What I want to understand now is:

• What are the details of the supply chain of process/inert gases (N2, CO2) of autoclaves in aircraft industry (Where does the gas come from, how is it utilzed for the autoclave process, What happens with the gas during and after the process?)
• Is CO2 currently used as inert gas in (industrial) autoclave processes for composite part manufacturing anywhere?
• What makes N2 better that CO2 [other (technical) reasons than money]?

I would be happy about any information as books/papers that help me to undrestand the above points

Regards.
